Magnelis® at the centre of ArcelorMittal Fos-sur-Mer’s first solar farm

ArcelorMittal Méditerranée recently inaugurated a photovoltaic farm on its site of Fos-sur-Mer, realised in partnership with EDF Energies Nouvelles. This solar farm of 15 hectares has a capacity of 12 MWc, equal to the annual electricity consumption of 7,400 citizens, half of the town of Fos-sur-Mer. Profil du Futur, a division of ArcelorMittal Construction, was in charge of the structure’s construction and used Magnelis®,a lead product of ArcelorMittal Europe – Flat Products for solar projects.

45,000 solar panels installed in 10 months

La Fossette solar farm is composed of 45,000 solar panels and its full construction required 10 months of work and up to 40 people. The solar panels structure was designed and produced by Profil du Futur in Horbourg-Wihr (near to Colmar, in France) and with steel produced by ArcelorMittal Bremen and coated with Magnelis®.

Based on DMSE’s specifications (the consulting firm mandated by EDF Energies Nouvelles), Profil du Futur proposed a structure designed in accordance with the Eurocodes standards that could meet all the needs (soil condition (determined by the G2AVP study), climatic loads, handling in the ground, modules fixing method, etc.).

The poles are the first steps in the installation of a solar structure. For La Fossette project, micropiles were the selected method, due to the nature of the ground (rocky with large blocks). This solution involves drilling the soil to a certain depth and to a certain diameter to install the pole and pour concrete into the hole around the pole. Before installing the micropiles, pulling tests are made to check how the poles will hold in the ground.

The photovoltaic modules of La Fossette were manufactured by the company TRINA and to realise the mounting parts which hold the modules on the structure, Profil du Futur partnered with Araymond who designed and manufactured the clamps.

Magnelis®, the reference material for solar projects

The structure of La Fossette solar farm was entirely made with Magnelis®, an ideal material for solar applications. Its remarkable corrosion resistance comes from its unique composition; developed by ArcelorMittal Europe – Flat Products, the coating includes zinc, 3.5% aluminium, and 3% magnesium. Magnelis® has a self-healing effect on cut edges and scratches which ensures excellent edge protection, even in the most hostile environments. When exposed to the environment, Magnelis® forms a very dense, zinc-based protective film. This film also forms on edges, welds, perforations, and scratches. It is almost impossible for the environment to penetrate this film.

La Fossette is the first project that EDF Energies Nouvelles realises with Magnelis®. Since 2012, Profil du Futur has made continuous efforts to make Magnelis® known as a suitable product for solar applications. This prescription as well as the 25-year guarantee were key factors which convinced EDF Energies Nouvelles to work with us.

Magnelis® wasn’t the only ArcelorMittal product used for this project. ArcelorMittal Fos-sur-Mer provided slag to consolidate the paths on the solar farm. Steel-making slag is a by-product of the steel production and often used in civil engineering to consolidate embankments.

A fruitful collaboration for Fos-sur-Mer

The completion of this project is part of the EDF Group's CAP 2030 strategy, which aims to double its renewable capacity by 2030. For ArcelorMittal Méditerranée, the aim is to facilitate the production of renewable energy by making parts of its industrial lands available. The last 5 years, the company invested €60 million for sustainability and remains attentive to the residents’ remarks.

Steel gives a new life to German bridges

Last year, German magazine Der Spiegel published an article about the collapse of old bridges in Germany - mostly due to heavy vehicles traffic - and the efforts made to reconstruct and modernise them. The reconstruction of the bridge "Demminer Strasse" in Neubrandenburg with ArcelorMittal beams shows that steel is an ideal bridge solution, providing a sustainable, quick and economic construction.

Composite solution for more resistant structures

To rebuild the bridge "Demminer Strasse" in Neubrandenburg, general contractor Matthäi Bauunternehmen Leezen opted for a filler beam deck solution. This kind of steel-concrete composite bridge is used for short and medium span superstructures with severe construction depth restrictions. The new two-span bridge has two separated decks for each traffic direction. It is built over railway tracks and provides further connections via the B96 road.

As ArcelorMittal Downstream Solutions successfully collaborated with Matthäi Bauunternehmen Leezen for a precedent bridge project in Schwerin, we won the contract in May 2016 and delivered H-profile wide flange beams in grade S355M with a profile depth of 900 mm each. Due to the closely spaced beams and prefabricated fibre-cement elements, which are placed on the lower flanges, no additional formwork or falsework for the concrete between the beams was needed. Thus, traffic interference below the new bridge was strongly reduced and expensive closure times for the railway line could be limited to only few nights.

Sustainable beams from Luxembourg

The 19 and 31-metre-long beams were produced by ArcelorMittal Europe – Long Products' mill in Differdange (Luxembourg). Afterwards, they were cut and welded with transversals (IPE 400 S235JR) by Downstream Solutions in Bad Oldesloe (Germany). The thermomechanical rolling process of the high quality S355M grade associated with the anti-corrosion coating applied on the beams will ensure the longevity of the structure.

The beams, like most of our steel beams used in bridge construction, were made of scrap. This once again demonstrates the sustainability of steel, which can be recycled infinitely many times while retaining its properties.

Downstream Solutions and ArcelorMittal Europe – Long Products coordinated their deliveries with the customer and Deutsche Bahn, ensuring that assembling of the beams could take place at night in July without any problems. The construction of the bridge will be completed in the first or second quarter of 2018.

On September 17 2015, the steel at U.S. Bank Stadium topped off, marking a major milestone in the construction of this new stadium, which has been constructed with 3,080 tonnes of our HISTAR® beams. Now, almost 2 and a half years later, it hosted the most important American Football event - with the Philadelphia Eagles as the big winners!

A roof 30% lighter

The trusses supporting the roof of the U.S. Bank Stadium were built using 3,080 tonnes of HISTAR® beams in grade 65 ksi. Produced in Differdange (Luxembourg), HISTAR® was the best solution for this project, as it enabled reduction of the weight of the roof by more than 30%. Finishing the steel erection marked more than 70% completion for the entire stadium project.

Exceptional design

U.S. Bank Stadium, home to the Minnesota Vikings NFL team, has an estimated construction cost of $ 1 billion and will have a capacity of 65,000 people. The stadium features a translucent fixed roof and five 29-meter-tall pivoting glass doors, which serve as a grand entrance to the facility and let in ample amounts of natural light. As 60% of the roof structure is transparent, stadium users will view the sun and sky throughout the year while staying in a climate-controlled environment.

The stadium was officially inaugurated in July 2016.

DUO in Singapore: a new landmark built on strong Histar® foundations

Located in the vibrant cultural and heritage district of Bugis in Singapore, DUO is a new real-estate development which opened its doors on 15 January 2018. This high rise has 2,082 tonnes of HISTAR® steel sections in its foundations, with the steel produced by ArcelorMittal Europe – Long Products. The use of our steel sections allowed the contractor to save both time and weight.

DUO comprises residences, offices, a hotel and retail space. It is designed by German-born Ole Scheeren, the architect behind the design of landmark projects such as the CCTV headquarters in Beijing, the MahaNakhon, Bangkok’s tallest skyscraper, as well as The Interlace, iconic residential development in Singapore and World Building of the Year in 2015.

Weight saving of 20% thanks to HISTAR®

ArcelorMittal contributed to the construction of the DUO Residences tower, which is still under construction. We supplied 2,082 tonnes of HISTAR® 460 steel sections produced in Differdange, Luxembourg, which were used to build the foundations of the tower using the top-down method.

What is the top-down method?

The top-down method is a composite method to build foundations. King post piles are put in the ground and while digging around them, slabs of concrete are put on top of them. At the same time, construction of the top structure starts. When arriving at the bottom, concrete is put around the king post piles for fire resistance. When the foundations of the building are completed, the building is already partially built, resulting in reduced construction time for the contractor.

The top-down method using our steel sections offers many advantages:

Weight saving of 20% compared to grade S355M (instead of using 2 sections in grade S355M, only one section in grade S460M/HISTAR® 460 was necessary)

Smallest hole to drill in the soil

Less fabrication work

No splicing needed

Fast to install

An impressive panorama of Singapore

Located in the centre of Singapore, in a neighbourhood that is home to historical sites and national monuments, the DUO project is composed of two towers, DUO tower (39 floors) and DUO Residences (49 floors). DUO is developed by M+S Pte Ltd, owned by Malaysia’s strategic investment fund, Khazanah Nasional Berhad and Singapore’s state-owned investment company, Temasek Holdings.

ArcelorMittal and the Fonds Kirchberg announced the winner of architecture contest to design new headquarters for the world’s leading steel company

“What I personally love is that this building visibly features steel, which is so often hidden from view. In fact, we believe that no other building of this size and scale has been designed specifically to feature steel throughout. Wilmotte & Associés have developed a truly innovative design that shows how beautiful steel is.” Aditya Mittal.

ArcelorMittal and the “Fonds d’Urbanisation et d’Aménagement du Plateau de Kirchberg,” (“the Fonds Kirchberg”) have announced on December 13 that the architectural practice Wilmotte & Associés Architectes (“W&A”) is the winner of the architectural consultation to design ArcelorMittal’s new global headquarters building in Luxembourg.

W&A was selected by a nine-person jury chaired by Aditya Mittal, CFO of ArcelorMittal and CEO of ArcelorMittal Europe, following a highly competitive process with designs proposed by many of the world’s leading architects.

Other landmark buildings designed by W&A include the Ferrari sporting management centre in Maranello, Google’s UK headquarters in London, the LVMH corporate headquarters in Paris and the five-star Mandarin Oriental Hotel also in Paris.

The ambitious winning design - which was just unveiled in Kirchberg, Luxembourg today - is primarily steel and glass, and will showcase the diverse benefits of steel over other building materials* as well as highlighting the use of steel in ‘green’, sustainable construction. As well as being ArcelorMittal’s headquarters, housing around 800 employees, some of the space will be leased for other uses. There will also be a restaurant, sports facility and 200 seat auditorium available to the public.

Innovative design

W&A’s design responds to a detailed brief to design a modern, sustainable building that harnesses all the potential of steel from top to bottom. The result is a truly unique building that includes numerous design firsts, including innovative new products and features that are the result of a close collaboration between the designer and ArcelorMittal’s research and development teams. Technical innovations include:- A fluid and flexible ground floor space featuring no columns, something that is only possible with steel thanks to the use of a suspended steel exoskeleton - An integrated flooring system fully designed in steel which removes the need for false ceilings, resulting in high quality acoustics and improved aesthetics- A curtain wall completely designed in steel which results in a lighter, more airy building due to steel’s higher strength and superior elasticity- New section bars adapted from products designed for the automotive sector.

The W&A design also responds to ArcelorMittal’s desire to have a sustainable building that promotes steel’s contribution to the circulate economy. The building follows the “cradle-to-cradle” concept, meaning that it can be dismantled and nearly all the steel products re-used in a new building without the need for recycling.

It is also a low-carbon, energy-efficient building, and will be “BREEAM outstanding,” “DGNB Gold,” and “BBCA” certified. Environmental credentials including solar power generation – featuring 4000 square metres of ArcelorMittal steel photo voltaic cells on the roof - rain water management and automatic window opening for natural ventilation. It also features a bioclimatic public atrium, ventilated by the Canadian Well system, which naturally cools the air in summer and heats it in winter. The atrium is designed to evoke the Luxembourg countryside and will feature trees and plants in a woodland style that also bring environmental benefits, acting as a buffer for the temperature. Further green space will be created by setting the building back from the limit of the plot, creating new outdoor public spaces. The building will also be certified by a Gold level “WELL” label.

Testimonies

Speaking in Luxembourg at an event to announce the winner, Aditya Mittal, chairman of the jury, said: “Taking the decision to invest in a new headquarters shows ArcelorMittal’s long-term commitment to Luxembourg. As the world’s leading steel company, it is also a great opportunity to have a new headquarters that showcases the flexibility, creativity and sustainability of steel as a construction material. All the architects that participated in the competition submitted interesting designs and on behalf of my colleagues on the jury, I would like to thank them all for their creativity. Ultimately though we could only select one project and W&A stood out for their complete respect of every aspect of our brief, including practicality, aesthetics, economics and sustainability, as well as their enthusiastic engagement with our R&D team. They have developed a truly innovative design. What I personally love is that this building shows the beauty of steel, which is so often hidden from view. In fact, we believe that no other building of this size and scale has been designed specifically to feature steel throughout. And, equally important, it will be a great place to work for our employees, a fantastic platform to show our customers what steel can do and an exceptional open space for visitors to this part of the city.”

Jean-Michel Wilmotte, Architect, President of W&A, said: “To be asked to design a new steel-based headquarters for the world’s leading steel company is an important commission. I love working with steel and am confident that we have developed a design that will showcase the very best of the material. I am particularly excited about the ambition of the building, which is to show how creativity, coupled with modern techniques, can advance the sustainability, economics, and practicality of modern office building design and so improve the lives of those who work and interact with it. I hope that the employees of ArcelorMittal will be proud of the building and will enjoy coming to work there for many years and decades to come.”

Michel Wurth, President of ArcelorMittal Luxembourg, added: “As a Luxemburger, I’m proud and excited that such a forward-thinking design will be built here largely with steel made in Luxembourg. Our steel features in so many iconic buildings around the world, it’s great to have an opportunity to create another one here in our home country. I believe W&A’s design fully captures the atmosphere of tomorrow which is appropriate for ArcelorMittal as a company on the cutting edge of its industry and will also provide a great place for our employees to work. It will be a new addition to the Kirchberg plateau and of course we will work closely work with the municipality of Luxembourg during the planning phase to fully integrate this new building into the already iconic urban landscape and skyline."

How did it start?

The consultation was initiated in February 2017 following ArcelorMittal’s decision in April 2016 to build a new head office in Luxembourg. ArcelorMittal is the principal industrial employer of the Grand Duchy with over 4,000 employees. The construction of a new, landmark headquarters building illustrates the Group’s commitment to maintaining its presence in the country, where the company has not only its head offices, but also seven industrial sites producing or processing steel, and developing steel solutions for the construction, automotive, general industry and agriculture sectors of the economy.

In the first phase, eight internationally renowned practices were invited to submit initial designs on April 27 and 28. Bernard Tschumi Architects, Foster + Partners, JSWD Architekten, Massimiliano Fuksas Architecture, Rafael Vinoly Architects, Rem Koolhaas OMA, Von Gerkan, Marg and Partners and Wilmotte & Associés were the architects included. In the second phase, three shortlisted practices – Foster + Partners, Rem Koolhaas OMA, and Wilmotte & Associés - were asked to develop a more advanced architectural design. These were then submitted to the jury which evaluated the proposals and then recommended Wilmotte & Associés to ArcelorMittal and to the Board of Fonds Kirchberg as the selected winner.

Ground breaking is expected during the summer of 2019 with completion in the last quarter of 2021.

How will employees be engaged in the process?

A working group – including HR representatives from ArcelorMittal – has been focusing on the integration of workplace challenges in the conception of the building for several months. Workshops will be organized with ArcelorMittal employees to deal with occupational wellness.

*This includes the ability to include additional storeys without compromising ceiling height, due to reduced floor thicknesses; fewer internal columns due to the strength of the most modern steel beams, permitting more flexible internal layouts; and, due to the lighter weight of steel buildings as opposed to those using conventional materials, less deep foundations, bringing timing and cost benefits. Use of steel also brings efficiency to site operations given that even the most complex forms are pre-fabricated off site and only come to site for assembly. Compared to traditional construction methods, this saves time and manpower on site, and lessens road congestion caused by deliveries.

Your ASOS order is on its way…courtesy of ArcelorMittal

If you are not familiar with the brand, ASOS is the biggest online-only clothing retailer in the UK with 14.1 million active customers and a huge catalogue composed of 80,000 branded and own-brand products. ArcelorMittal provided Hacierba® liner trays and 2,000 tonnes of sections for the construction of ASOS first warehouse outside Great Britain.

British online retail company ASOS just started the activity of its first warehouse outside Great Britain, located in Großbeeren, in the south of Berlin. It was designed by Alcaro (a specialised investor for logistics facilities) with a roof structure built with ArcelorMittal Europe – Long Products steel provided via steel fabricator Stahlbau Süssen. ArcelorMittal Construction is also a contributor to the project with the supply of Hacierba® 150/600 SRSR liner trays for the façade of the warehouse.

Challenge accepted

The construction of this logistics centre was divided into two phases. For the first phase, which took place in 2016, four halls with a total surface of 46,000 m² were built. We had to deal with strict requirements for the construction.

First, ASOS demanded a maximum clear height to be able to place very high shelves in the hall, but due to fire safety considerations, the total height of the halls was limited. This challenge resulted in the development of a roof structure with a span of 26 metres and a height of one metre maximum which would contain the whole equipment of the building (electric cables and lamps, air conditioning, heating and sprinklers).

Second, the investor required the building to be certified by DGNB (Deutsche Gesellschaft für nachhaltiges Bauen), German Sustainable Building Council. Consequently, A.C.B.® beams were the best solution as they could meet all the requirements.

For the second phase, four new halls are being built, still using A.C.B.® beams, but this time the beams were made 6 cm higher to support additional loads due to the presence of solar panels on the roof.

ArcelorMittal’s sustainable and cost-efficient solutions

ArcelorMittal Construction’s Hacierba® liner trays provide very good load bearing capacity. They are the inner shell of the façade, bearing the wind loads and providing heat insulation of the building thanks to a mineral wool lining. It is an economic, lightweight solution that is easy to assemble. Furthermore, we could provide the customer very short delivery times.

ArcelorMittal Europe – Long Products and our technical department Tecom worked closely with customer Stahlbau Süssen to develop ACB.® beams that would fulfil all the requirements. ACB® beams allow for a very efficient structure using only few resources and they are perfectly tailored to the loads of such a structure.

Moreover, the structural shapes used to produce them were made from 98% scrap material, with 70% of that being recycled steel. And they can be used after dismantling of a structure as construction elements in new projects.

In total, we supplied for the whole project 376 tonnes of sections without finishing and 1,665 tonnes of 13-metre ACB® beams which were painted in red (the corporate color of Alcaro) and with the contact faces of the head plates covered with a special friction-resistant coating.

Just-in-time deliveries

As the construction site and the ArcelorMittal Construction’s site in Landsberg are only 145 km apart, ArcelorMittal could provide a short delivery time for the liner trays; resulting in low transport cost for the customer, as well as less Co2 emissions.

For the beams, the delivery was just-in-time by trucks. The beams were bolted together two by two on the construction site and put in place as a roof girder. Logistics was even simplified on our side since our finishing and coating workshops are both located around the premises of the Differdange mill in Luxembourg; making internal logistics by rail simple and efficient. As for the other sections we supplied, they were produced in Differdange and in Dabrowa, Poland. The customer did the finishing and painting and delivered them directly to the construction site.

The first part of the building is already in use and the second part is expected to be completed in January 2018.

HISTAR® 460 at the heart of Sydney’s first six-star luxury hotel resort

Located in Darling Harbour, Sydney, as part of the Barangaroo Development, the Crown Sydney Hotel Resort is currently being built with ArcelorMittal’s HISTAR® steel. This future integrated resort will include a six-star international hotel and a VIP gaming facility, scheduled to open in 2021 and offering breathtaking views to the Sydney Harbour Bridge and the Sydney Opera House.

A new landmark for the city of Sydney

Crown Sydney is a luxury six-star hotel resort and is currently being built at Barangaroo South on Sydney Harbour, in Australia. It is a huge project and will be the first six-star international hotel to be built in Sydney.

HISTAR® king post columns to support the building

ArcelorMittal Europe – Long Products have supplied, through Eurostructures, 350 tonnes of HISTAR®columns to be installed as king posts into bored piles as part of the foundations of the resort. Our king post columns have been supplied to Piling Contractors Bauer Australia Joint Venture, specialist contractors for the foundations, via steel constructor J Steel, who has been representing ArcelorMittal in Australia and in the Australasia region for many years.

Our king posts, made from HISTAR® S460M steel, produced in Luxembourg, were installed into piles, drilled into the bedrock, to support the weight of the podium above. They allowed 20% weight savings and reduced sizes to simplify installation Moreover, to reduce fabrication in Australia, they were rolled in single lengths to eliminate splicing and Eurostructures cut the plunge columns to final length before shipment to Australia.

The Crown Sydney Hotel Resort has everything it takes to become a landmark building and a key tourist attraction for the city of Sydney and we are proud to participate in this project.

Elster Bridge: Steel paves the way to a nature reserve in Germany

In Osendorf (Germany), ArcelorMittal Europe – Long Products contributed to the construction of a composite bridge built with our Prefabricated Composite Beams (PreCoBeams), ensuring an external reinforcement for the concrete bridge. It is the first hot-dip galvanised composite dowel construction in Germany.

PreCoBeams: a competitive and sustainable solution

Due to the flood risk in the area, the new bridge required to be built without a pillar, as a single-span frame with a length of 21 metres.

PreCoBeams were an adequate solution to this requirement. It is a relatively new bridge construction method which involves heavy beams that are oxycut longitudinally in two T-sections with a specific geometry.

On the one hand, it creates the special bond with the concrete and thus substitutes the welded shear studs in standard solutions, and on the other hand, it improves the beam's fatigue performance.

This economic bridge solution has many advantages:

high degree of prefabrication, reducing installation time

reduction of coating surface

no need for studs or welding

very sustainable lifecycle and lower maintenance costs due to lifetime corrosion protection

high safety standard in case of vehicle (trucks) impact

All the steel used for the bridge was produced by ArcelorMittal Europe – Long Products’ mill in Differdange (Luxembourg). To create the PreCoBeams, 7 tonnes of 20-metre HD320x300 profiles in the grade S355ML were cut by our Beam Finishing Center Eurostructures. This was a great advantage for ArcelorMittal, as we were able not only to sell the HAV products, but also to take care of the finishing thanks to the experience of Eurostructures.

One year from start to finish

The new bridge is located in Osendorf and transfers a rural road across the Elster river to a nature reserve. The bridge is 21 metres long, 4.5 metres wide with a road width of 3.50 metres. It is actually a replacement solution for the Elsterbrücke bridge as the three-span structure, built in 1950, couldn’t be reconstructed due to flood damage.

Overall, it only took one year to create and build this new solution from the first meeting in April 2016 to the opening of the bridge in the spring of 2017.

Since the early 2000s, Grand Line has been working with organic coated steels from ArcelorMittal Europe – Flat Products for its range of roofing tiles and accessories. The products are used by Grand Line’s customers for the roofs of cottages and low-rise constructions. Today Grand Line is utilising ArcelorMittal’s Granite® HDX for its Quarzit range because it offers excellent performance in the harsh Russian climate.

Grand Line began buying Granite® HDX when its customers started demanding a high-performance roofing solution with a polyurethane coating. “At the time, another steelmaker was offering this solution so our customers were naturally interested,” explains Sergey Namestnikov, head of marketing. “We searched for a product that would offer the same outstanding colour and gloss retention and found Granite® HDX from ArcelorMittal for our Quarzit range.”

Colour selection suits local aesthetics

Granite® HDX is available in a wide range of colours and metallic shades, however, Grand Line uses a limited selection, notes Sergey Namestnikov: “From the Granite® HDX colour palette we mainly choose dark colours such as moss green, copper brown and chocolate brown, which ArcelorMittal colour-matches for us to ensure consistency. On top of this standard offer, we ask for special colours including copper which suit the aesthetics of our local market.”

In addition to roofing solutions, Grand Line creates metallic siding and corrugated profiles. “Many of these products are created with Access Standard and other steels from ArcelorMittal’s Granite® range including Standard, HD, Storm, and Deep Mat,” says Sergey Namestnikov. “And we make gutters out of Granite® Rain HDS.

Innovation days facilitate knowledge exchange

Grand Line has a stand where ArcelorMittal materials are tested in natural conditions to ensure their suitability for the Russian climate, notes Sergey Namestnikov: “This allows us to have a continuous exchange with ArcelorMittal about the corrosion tests, and to provide them with feedback from the end users of our products. Since 2014, we have held innovation days at least once a year to facilitate the feedback process. We are in contact with ArcelorMittal’s technical support teams on a regular basis for any immediate questions or issues.”

Grand Line

Founded in 1965, Grand Line has grown to become one of the largest producers of building materials for cottages and low-rise construction in Russia. The company employs more than 3,000 people at its seven plants in Russia. Grand Line’s Vorsino plant is one of the most advanced in Russia and utilises a range of technologies not found elsewhere in the country. Grand Line exports to every region of the country as well as to Belorussia, Kazakhstan, and Latvia.

ArcelorMittal gets nod from World Economic Forum for integrating circular economy principles into its business model

The world’s most prestigious award programme for the circular economy, The Circulars, has highly commended ArcelorMittal for demonstrating leadership and innovation by applying circular economy principles to its business models.

By collaborating with internal experts, those from academia and its customers, ArcelorMittal is finding ways to make transformational changes to the way it does business, as it seeks to achieve its ambition of becoming a zero-waste company. Some of the ways it is doing this, acknowledged by the commendation, include:

Partnering with technical and industry leaders to develop and scale up ground-breaking carbon capture and utilisation technology, resulting in products like Steelanol, a bio-fuel made from waste carbon monoxide, with the help of microbes. This high-grade ethanol will then be used for transportation and to make plastics. The company anticipates Steelanol could create 2000 direct and indirect jobs and generate an income of 300 million euro a year by 2025, while significantly reducing greenhouse gas emissions – 5 million tonnes worth a year by 2025.

Manufacturing ECOCEM, a low carbon cement, from its slag and selling it directly to customers. In France alone, this practice has already reduced the cement industry’s CO2 emissions by nearly two million tonnes, and from 2018 onwards it is projected to further reduce those emissions by a further one million tonnes a year. Selling this by-product generates over 100 million euro in revenue each year.

Paving more than 650 km of country roads across 20 Brazilian municipalities with over 1.5 million tonnes of Revsol and Revsol Plus. These products, made from slag, a by-product of the steelmaking process, replace natural non-renewable resources such as gravel.

Allocating additional resources to detailed life cycle assessment of its products and developing a new sustainability assessment tool.

Designing innovative processes and products to maximise efficiency and minimise waste in its own production and those of its customers.

Stretching product lifecycles by leasing sheet piles for short term projects, rather than selling them – and then leasing them again. The company’s comparative studies show reusing sheet piles has 86% less global warming potential than permanent steel sheet piles and 90% less global warming potential than a concrete retaining wall. Similarly, through the circular building, exhibited at the London Design Festival 2016, the company demonstrated the concept of steel reuse for entire steel structures, given they are designed, dismantled and reused with the circular economy in mind.

Torrefing waste wood and using it to replace coal in its blast furnaces, harnessing and using energy that would otherwise have been lost. In doing so, the company expects to recycle two to four million tonnes of waste wood each year by 2025, saving it approximately 100 million euro a year.

The Circulars 2018, an initiative of The World Economic Forum and The Forum of Young Global Leaders, run in collaboration with Accenture Strategy and given at the World Economic Forum’s Annual Meeting in Davos. The award recognises individuals and organisations from around the world who are making notable contributions to the circular economy.

Alan Knight, General manager, head of corporate responsibility and sustainable development said, “Being highly commended by the Circulars 2018, is a fantastic achievement and highlights how far we have come as a steel company to change not only the way we do things, but also the way we are perceived as a corporate citizen. We have long talked about the value steel brings to people’s lives and its unparalleled recyclability, but now we are finding ways to take those ideas further and become a zero-waste company by integrating circular economy principles into everything we do.”

Hilti-ArcelorMittal: a strong partnership

Interest in the use of high strength steels (HSS) is growing rapidly in the global construction sector. That’s because high strength steels offer promising weight reductions, increased spans, and improved load-bearing capacity compared to alternative materials.

Benefits of using ArcelorMittal’s high strength steels for structural profiles

Cold-formed profiles made from HSS are used for many applications including roofs and facade structures, light steel framing, prefabricated modules, storage and racking systems, and silos. With new construction steel grades up to S550GD+Z, HSS offer profilers, installers and end users great potential for structural improvements. If the same thickness of steel is used, design stresses can be increased or longer spans can be achieved. Alternatively, the thickness of profiles can be reduced, resulting in significant weight savings which also reduce production and transportation costs.

European building codes and standards are being developed to include these new HSS grades. The following standards have already been revised:

Eurocode 3, Parts 1-12 have been updated to allow the use of steel grades up to S700.

EN 10346:2015 for continuously coated steel flat products for cold forming has been updated to include several new grades such as S390GD+Z, S420GD+Z, and S450GD+Z. New zinc-magnesium coatings such as Magnelis® have also been added.

A fruitful partnership between Hilti and ArcelorMittal: New self-drilling screws from Hilti increase performance

Early in 2017, Hilti and ArcelorMittal initiated a technical collaboration to improve the performance of self-drilling screws for HSS. The screws are typically used to fasten sandwich panels to the cold-formed profiles of building structures.

The collaboration between Hilti and ArcelorMittal has resulted in the development of the first worldwide portfolio of fastening elements to connect sandwich panels and HSS profiles (up to S450GD). The new screws are backed by a European Technical Approval (ETA-13/0179).

The technology combines a hardened carbon-steel drill tip and stainless steel shaft. The result is improved installation speed and long-term endurance in corrosive environments.

Other applications for the screws are being tested including long-span decking and racking. Once approved, they will enlarge the applications for these screws and enable one-step fastening of HSS profiles.

IBU (Institut Bauen und Umwelt e.V.) has published an Environmental Product Declaration (EPD) for single-sided road barriers made with high strength low alloy and structural steels coated in Magnelis®. The EPD covers barriers which are made from steel grades HX340LAD, HX420LAD, S250GD, or S350GD, with ArcelorMittal’s Magnelis® ZM310 metallic coating.

The EPD applies to one running metre of a single-sided barrier including the support post. The thickness of the steel ranges from 2.8 to 8.0 mm depending on the design.

The barriers covered by the EPD meet the H1W3A level of the EN 1317-2:2010 European standard for road restraint systems. H1 barriers are designed to contain a 10,000-kilogram vehicle travelling at 70 kilometres per hour. The EPD is based on data collected from ArcelorMittal’s mills in Bremen (Germany) and Ostrava (Czech Republic).

An EPD is an independent and transparent way of communicating about the environmental performance of a product or system. The content is derived from a life cycle assessment (LCA) and typically evaluates all phases of the product’s life including supply of the raw materials, production, and end-of-life recycling. The EPD also contains information about the energy use, efficiency, emissions, and waste generation during the product’s manufacture, service life, and recycling.

Bacacier is one of France’s leading manufacturers of steel roofing and cladding solutions for the building and construction sector. With an eye on constant innovation, Bacacier is always looking for new aesthetic steel solutions to enhance its range of products. Thanks to a close relationship with ArcelorMittal Europe – Flat Products, Bacacier was a key partner in the development of Granite® Quartz in France and is now incorporating it into their latest products.

Bacacier is constantly innovating its product range to bring the best steel solutions to its customers. Unlike many of its competitors, Bacacier creates products for both professionals and the fast-growing do-it-yourself (DIY) market.

A durable and attractive solution

Bacacier has recently created a new range of construction materials using Granite® Quartz from ArcelorMittal. “We are always looking for new finishes and Granite® Quartz was a good solution thanks to its look and feel, and scratch resistance,” explains Luc De Deygere, purchasing director of Bacacier. “Scratch resistance is very important – particularly for our roofing solutions.”

Bacacier was closely involved in industrial-scale trials of Granite® Quartz notes Luc De Deygere: “ArcelorMittal does not just sell us coils. We sit with their technical people and explain our needs. Together we can co-engineer products for the future. When ArcelorMittal first proposed the idea of Granite® Quartz, we immediately saw the potential of this durable and attractive solution.”

Although Bacacier has only recently introduced Granite® Quartz to its professional clients, sales are steady says Luc De Deygere: “It’s only been on the French market for a few months, so customers are still becoming aware of Granite® Quartz. But their initial reactions have been overwhelmingly positive. We see a bright future for Granite® Quartz as part of our portfolio.”

Bacacier’s Tuile R PRO system simplifies the construction process and comes with a 20-year guarantee.
